Abstract
This work studied suspicious and authentic artworks by Brazilian painters Ivan Serpa, Ismael Nery, and Iberê Camargo by XRF, FTIR, OM, and MA-XRF techniques. The studies made it possible to verify that all suspicious artworks are counterfeit artifacts. The analyses were conducted in situ, and different approaches were applied for data treatment. For example, principal component analysis and spectral deconvolution were performed on the XRF data. From these methods, it was possible to verify that the suspect artworks by Ivan Serpa and Iberê Camargo have different materiality than the authentic paintings. Additionally, MA-XRF images did not reveal the presence of a polychrome preparation layer in the suspicious paintings by Ivan Serpa. The suspect artworks from Ismael Nery exhibited a Ca-K/Ti-K ratio that indicates they were created on a low-quality paper support, which is not suitable for paintings. The differences in materials used in the suspicious and authentic artworks are further supported by the FTIR and OM results. In addition to the physicochemical analysis, the paintings were studies graphotechnical examinations, financial evaluations, and artistic analyses that demonstrated they were counterfeit artifacts. The results of the analysis demonstrate how physicochemical techniques can contribute to the forensic investigation of paintings. However, this work highlights the importance of applying distinct treatments to the XRF data in order to accentuate the differences between the suspect and authentic artworks.

Abstract
Burn injury as a form of hetero or auto-aggression accounts for a significant amount of admissions to a Burn Care Unit, with epidemiologic and clinical specificities. To investigate the differences in risk factors, psychiatric comorbidities, injury severity and mortality among adult patients with accidental or intentional burns, we analyzed routinely collected data from a Central Hospital Burn Unit over a period of 6 years (January 1st, 2010 to December 31st, 2015). We identified 22 intentional burn patients (5%) among all the admissions to our Burn Unit. When compared to the accidental burns, the intentional burn patients are significantly younger (45.7±14.7 vs. 54.9±19.9), have a bigger percentage of body surface area burned (35% vs. 14%), have a higher incidence of inhalation burn (50% vs. 22.8%) and higher mortality (18.2% vs. 6.1%). Fifty-five percent of cases of intentional burns were self-inflicted. Self-inflicted burns have a worse prognosis than hetero-aggressions (inhospital mortality 25% vs. 10%). Psychiatric comorbidities were largely more prevalent in the intentional burn patients (59% vs. 6.6%), namely mood disorders. Compared to patients with accidental burns, intentional burn patients have worse clinical condition and prognosis. A multidisciplinary preventive approach, looking at the specificities of the violent nature of the lesions and identifying risk groups may reduce the incidence and severity of this type of burns.

Abstract
Third-degree burns of the lower extremities are among the most difficult burn injuries to treat as they frequently expose bone, tendons or articular surfaces. Coverage with a flap is the ideal treatment, but local tissue is often unavailable, and free flaps require sophisticated equipment and perfect microsurgical technique. We demonstrate a treatment option to obtain a stable cutaneous coverage for this kind of injury, consisting in an association of skin grafts, amniotic membrane and bilaminar dermal matrix templates. This combined treatment proved to be an excellent option to cover a wide area of tibial exposure with low donor site morbidity and good functional and aesthetic results. This shows that artificial dermis is a good alternative for treating bone exposure, especially in patients for whom a classic flap reconstruction is not suitable.
